Operation
Power and activity indicators
On the front panels of all
modules are small recessed
indicators which provide
confirmation of power and
activity for each channel, as
follows:
• Constant red
- power
applied, no communication
activity.
• Flickering red
- power
applied, mouse or keyboard
activity occuring.
• Slow flashing red
- module is
in flash upgrade mode.
Note: All modules contain
internal automatic cut-out fuses
to protect against power surges.
To reset, remove power (or, for
the LOCAL module, the multi-
cable connection) from the
module for one second and then
reconnect.
General use
In use, the Wizard modules should be almost transparent - the system and its
peripherals should operate almost exactly as normal, the only difference being
that they are duplicated (see ‘User arbitration’ below) and one set is now up to
200 metres away.
User arbitration and keyboard indicators
During operation, both of the connected video monitors continuously receive
the output from the host system. Control of the host system is arbitrated by the
Wizard modules on a first come, first served basis. In the idle state, control is
available to both users and their keyboard indicators both show the current Num
Lock, etc. conditions of the host system.
At the moment that a key is
pressed or a mouse is moved,
the keyboard and mouse of
the other user are temporarily
locked-out (the video images
remain). The keyboard
indicators of the locked-out
user then begin to flash to
confirm their status
ð
After two seconds of
inactivity from the user
currently in control, the modules return to their idle condition and re-instate the
keyboard indicators of the locked-out user.
Visible image shadows
In some installations, you may see some ‘shadows’ to the right of high contrast
screen characters. This can be caused by an incorrectly selected sharpness setting
and it may be necessary to make adjustments to correct this. Please see ‘Image
controls - sharpness and brightness’ in the ‘Special configuration’ section.
